drm-misc-next for v6.19: UAPI Changes: Cross-subsystem Changes: - fbcon cleanups. - Make drivers depend on FB_TILEBLITTING instead of selecting it, and hide FB_MODE_HELPERS. Core Changes: - More preparations for rust. - Throttle dirty worker with vblank - Use drm_for_each_bridge_in_chain_scoped in drm's bridge code and assorted fixes. - Ensure drm_client_modeset tests are enabled in UML. - Rename ttm_bo_put to ttm_bo_fini, as a further step in removing the TTM bo refcount. - Add POST_LT_ADJ_REQ training sequence. - Show list of removed but still allocated bridges. - Add a simulated vblank interrupt for hardware without it, and add some helpers to use them in vkms and hypervdrm. Driver Changes: - Assorted small fixes, cleanups and updates to host1x, tegra, panthor, amdxdna, gud, vc4, ssd130x, ivpu, panfrost, panthor, sysfb, bridge/sn65dsi86, solomon, ast, tidss. - Convert drivers from using .round_rate() to .determine_rate() - Add support for KD116N3730A07/A12, chromebook mt8189, JT101TM023, LQ079L1SX01, raspberrypi 5" panels. - Improve reclocking on tegra186+ with nouveau. - Improve runtime pm in amdxdna. - Add support for HTX_PAI in imx. - Use a helper to calculate dumb buffer sizes in most drivers.

drm/amdgpu: update the functions to use amdgpu version of hmm

2025-10-13T18:14:36Z

At times we need a bo reference for hmm and for that add a new struct amdgpu_hmm_range which will hold an optional bo member and hmm_range. Use amdgpu_hmm_range instead of hmm_range and let the bo as an optional argument for the caller if they want to the bo reference to be taken or they want to handle that explicitly.

drm/amdgpu: clean up amdgpu hmm range functions

2025-10-13T18:14:28Z

Clean up the amdgpu hmm range functions for clearer definition of each. a. Split amdgpu_ttm_tt_get_user_pages_done into two: 1. amdgpu_hmm_range_valid: To check if the user pages are valid and update seq num 2. amdgpu_hmm_range_free: Clean up the hmm range and pfn memory. b. amdgpu_ttm_tt_get_user_pages_done and amdgpu_ttm_tt_discard_user_pages are similar function so remove discard and directly use amdgpu_hmm_range_free to clean up the hmm range and pfn memory.

drm/amdgpu: use user provided hmm_range buffer in amdgpu_ttm_tt_get_user_pages

2025-10-13T18:14:28Z

update the amdgpu_ttm_tt_get_user_pages and all dependent function along with it callers to use a user allocated hmm_range buffer instead hmm layer allocates the buffer. This is a need to get hmm_range pointers easily accessible without accessing the bo and that is a requirement for the userqueue to lock the userptrs effectively.

drm/amdgpu: use hmm_pfns instead of array of pages

2025-09-23T14:22:31Z

we dont need to allocate local array of pages to hold the pages returned by the hmm, instead we could use the hmm_range structure itself to get to hmm_pfn and get the required pages directly. This avoids call to alloc/free quite a lot. Signed-off-by: Sunil Khatri Suggested-by: Christian König Reviewed-by: Christian König Acked-by: Felix Kuehling Signed-off-by: Alex Deucher

Give TTM BOs a separate cleanup function. No funktional change, but the next step in removing the TTM BO reference counting and replacing it with the GEM object reference counting. v2: move the code around a bit to make it clearer what's happening v3: fix nouveau_bo_fini as well Signed-off-by: Christian König Acked-by: Thomas Hellström Acked-by: Joonas Lahtinen Link: https://lore.kernel.org/r/20250909144311.1927-1-christian.koenig@amd.com
